AI Hedge Fund Situational Awareness Loses $30B in One Month Due to Leverage
Leopold Aschenbrenner, a young AI hedge fund manager and former OpenAI researcher, saw his firm Situational Awareness deliver gains of over 1,500% since its inception in 2024. By early 2026, the fund had grown to $45 billion in assets by investing heavily in companies tied to the AI data center boom and was up an impressive 439%. However, a sharp market correction hit these high-flying names hard. Aschenbrenner's use of four times leverage amplified both gains during the bull run but also losses when volatility returned. The fund suffered significant declines in its long positions on AI stocks as well as short positions against legacy software companies like Adobe. Margin calls from brokers overwhelmed Situational Awareness, nearly leading to liquidation before a $10 billion rescue deal with Citadel was struck. The fallout led to a 67% drop in the fund's portfolio value for July alone. Aschenbrenner took full responsibility and acknowledged that these losses were costly but could serve as valuable lessons moving forward.
